This is just a small update on my experiments with the Arduino. I implemented the runge-kutta-method for solving a multibody system a few weeks ago. So this is a working implementation of the standard 4th-order runge-kutta ODE (ordinary differential equations) solver for the arduino platform, something I haven’t seen elsewhere.

My main goal was to get a better grip on simulation speeds. Why is my simulation so slow? is a question I’m really thinking about a lot. Since I wasn’t able to find a good example of an arduino sketch for ODE solving online, this may be interesting anyway.
